FAQ
 

 

Q: What is a niobium ingot?

A: Niobium (aka Columbium) has a very high melting point yet low density and is corrosion resistant. It is has the largest magnetic penetration depth of any element, has superconductive properties, and a low capture cross section for thermal neutrons.

Q: Is niobium a precious metal?

A: Though niobium has a lot of characteristics of precious metals like it is rare, highly resistant to chemicals and difficult to refine, it is not a precious metal.

Q: How is niobium produced?

A: Niobium metal is produced by the aluminothermic reduction of the oxide followed by electron beam refining.

Q: How do you extract niobium?

A: Niobium can also be extracted from concentrated in metal and acid chloride solutions by using high- molecular spirits, octanol in particular. In contrast to alcylphosphoric acids, spirits are good extractors for hydrochloric acid, especially in the range of high HCI concentrations.

Q: How is the quality of a niobium ingot measured?

A: The RRR value of niobium is measured by comparing the resistivity of niobium at ~10 K (just above its transition temperature) to the resistivity at room temperature.

Q: What is the stability of niobium?

A: Niobium can form very stable carbides, nitrides, borides and silicides, possessing high interatomic bonding energies. Hence, niobium is used in the stabilization of stainless steels to prevent intergranular corrosion since it helps lowering the content of carbon in the steel.

Q: What are the storage requirements for niobium ingots?

A: They should be stored in a dry, clean, and protected environment.
